Application filed June 16, 190i.

T0 (tZZ whom, it may concern.-

Be it known that I, JOHN J HENNESSEY, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Improvements in Railway Rolling-Stock; and I do hereby declare that the following is a full, clear, and'exact description thereof.

My invention relates to structural peculiarities in railway-car underframing; and it consists in what is hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

' Figure 1 of the drawings is indicated by lines 1 1 in the second figure and represents a transverse section view of a portion of a railway-car, the underframing of which is made in accordance with my invention to have continuous metal center sills, theupper members of the double body bolster being also continuous; Fig. 2, a detail plan view, partly in horizontal section, this view being for the most part on the plane indicated by line 2 2 in the first figure; Figs. 3 and at, detail vertical section views longitudinally of the car, these views being respectively indicated by lines 3 3 and 4 4 in said first figure; Fig. 5, a transverse section view of said sills and a portion of a single bod y-bolster in assembly therewith; Fig. 6, a partly sectional view indicated by lines 6 6 in the seventh figure, and Fig. 7 a similar view indicated by line 7 7 in the fifth figure; and Fig. 8, a plan view, partly in horizontal section, on the plane indicated by line 8 8 in the seventh figure.

Referring by letter to the drawings, A indicates each of a pair of steel center sills; B, a side sill; 0, intermediate sills, and D an end sill of the underframing of a railway-car. The center sills are continuous from end to end of the car and connected to the end sills. The center sills are shown in the form of channel -beams set edgewise; but various other forms of angular beams may be utilized. In some constructions of the underframing a single metal center sill may be employed, but

preference is given to a pair of such sills, and

Serial No. 64,684. (No model.)

in practice the draft appliances of the car are fastened to the webs of said pair of sills 'direct or to Wooden facings securedto 'said webs between flanges of the same. In the accompanying drawings the center-sill flanges are outward; but they may be inward, or both outward and inward, it being practical to employ I-beam center sills.

By having the draft appliances arranged as above specified the shocks in buffing and the strains in pulling are directly in line with the continuous metal center sills, this being a very desirable feature in the art to which my improvements relate.

While I have shown side, intermediate, and end sills of wood, it is practical to have them of metal, and it is also practical to omit said intermediate sills. Strips E of wood are shown fast on the upper flanges of the continuous metal center sills, and the car-flooring is nailed to these strips and sills of like material; but if the side and intermediate sills are of metal they also will be provided with upper facing-strips of wood on which to nail said flooring.

The continuous metal center sills A have their webs provided with longitudinal slots 1), and upper continuous members F of bodybolsters extend through the slots under the intermediate and side sills, to which they are made fast, said intermediate and side sills being preferably mortised to fit said bolster members, that are of themselves preferably back-folded at the ends to provide shoulders, against which the extremities of the lower members G of said body-bolsters abut. This construction is well illustrated in Fig. 1 and serves to prevent shearing of the upper and lower members of the body-bolsters on bolts passing through the same. The slots in the center webs of the continuous metal center sills are flanked by stops H, abutting edges of the upper continuous members of the bodybolsters, these stops being preferably rightangle castings bolted to said webs upon either the inner or outer sides of same, as found most convenient or desirable, both positions being herein shown. Brace-blocks I J are arranged between the upper and lower members of the body-bolsters, and side bearings K are provided in connection with bolsters.

The double body-bolster herein shown has the center block and center-plate thereof in one casting L,'end branches of which are interposed between the upper and lower members of said bolster and bolted thereto, the construction being such that said casting abuts and stays the inner edges of said upper and lower bolster members, as is best illustrated in Fig. 3. Flanges c of casting L abut lower outer flanges of center sills A and have outer stop-shoulders cl in opposition to said center-sill flanges, as best shown in Fig. 1. The single body-bolster herein shown has a center casting L and center-plate M, separated by lower bolster member G, caught in recesses of said casting and plate, as best illustrated in Fig. '7. Side flanges c of casting L extend under center sills A, and lugs e of these flanges support space-blocks N, that lap. adjacent sill-flanges. Bolts f pass through the upper bolster member F, spaceblocks N, flange-lugs e of the center casting L, lower bolster member G, and ears 9 of center-plate M, as clearly shown in Fig. 5. The upper central portion of casting L has sung fit between the continuous metal center sills A, and upper stop-shoulders hof this casting oppose the edges ofthe adjacent upper member of the body-bolster. The side flanges c of said casting are extended in opposite directions longitudinally of the car, as shown in Fig. 8, to provide corresponding increase of support for the center sills,.and said flanges are shown provided with outer stop-shoulders d in opposition to adjacent center-sill flanges, as best shown in Fig. 6. In either form of body-bolster the outer stopshoulders of the center casting serve to increase the rigidity of the entire underframing herein set forth.

No claim is made for the structural peculiarities of the combined center block and center-plate casting L in the double bodybolster; but the detail of center casting L in the single body-bolster is part of the present improvements. However, the main features of these improvements is a preferably continuous metal center sill or plurality of such sills having web-slots and continuous upper members of body-bolsters extending through said slots, this being a construction that saves mutilation and consequent weakening of side and intermediate sills, the making of metal center sills in sections bolted to body-bolsters or the interposition of continuous metal center sills between parts of said bolsters joined thereto at the intersections, and there is no appreciable loss of strength due to the slotting of the center-sill webs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A metal center-sill underframing of a railway-car having the upper members of its body-bolsters continuous through sill-web slots, and stops on the sill-webs opposing edges of said bolster members.

2. A metal center-sill underframing of a railway-ear having the upper members of its body-bolsters continuous through sill-web slots, and center pieces of the bolsters provided with side flanges made with outer stopshoulders opposing sill-flanges.

3. A railway-car under-framing having a pair of metal center sills provided with webslots, the upper members of its body-bolsters continuous through said slots, and center pieces of said bolsters having side flanges that extend therefrom in opposite directions under against said sills lengthwise thereof.

4. A railway-car underframing having a pair of metal center sills provided with webslots, the upper members of its body-bolsters continuous through said slots, and center pieces of said bolsters having side flanges that extend therefrom in opposite directions un der said sills lengthwise thereof.

5. A railway-car underframing having a pair of metal center sills provided with webslots, the upper members of its body-bolsters continuous through said slots, center pieces of said bolsters having side flanges that extend therefrom in opposite directions under against said sills lengthwise thereof, and shoulders on said flanges of the center pieces opposing edges of sill-flanges.

6. A railway-car underframing having a pair of metal center sills provided with webslots, the upper members of its body-bolsters continuous through said slots, and stop-shoulders on the center pieces of said bolsters in opposition to edges of said upper members of same.

7. A railway-car underframing having a pair of metal center sills provided with webslots, the upper members of its body-bolsters continuous through said slots, side flanges on center castings of the body-bolsters under said sills and provided with lugs, and spaceblocks held intermediate of said upper bolster members and lugs of the center casting side flanges to lap sill-flanges.

8. A railway-car underframing having a pair of metal center sills provided with webslots, the upper members of its body-bolsters continuous through said slots, side flanges on center castings of the body-bolsters under said sills and provided with lugs, space-blocks on the lugs lapping'sill-flanges, and bolts extending through said upper bolster members, space-blocks, center-castin g flange-lugs, lower members of said bolsters and ears of bolster center-plates between which and said castings said lower members of the aforesaid bolsters are fitted. p 7
